Topic: Stacking with Avaya 5650-TD & 5510/20 (Read 2233 times)

Hi Looking to add a 5650-TD to our current stack of 5510/20 so that we can use the 10GB xfp between two buildings, But I'm not sure if stacking between these is possible with FW-6.6.x even when set to operate as a hybrid

The stack as is has the 5520-PoE as the base and has 3 additional 5510 in the stack, so looking at removing one of the 5510 then make the 5650 the base, need to leave the 5520 in as its providing power to some AP's

It's been a little while since I used a hybrid stack, but I recall they had to be running the same firmware version across all the switches. The last version that supported the 5510/5520/5530's and 5600's was v6.3.6. So I don't think this is going to work for you. If you need 10Gig ports, you may have to look for a 5530 that has the two XFP ports on it.

My experience with hybrid stack, going back to ES450 stacked with BPS2000, is that it's a solution best left alone. Stack 5500s with 5500s and 5600s with 5600s. 5510 has limits on a number of features compared to the 5520/5530, I have some traumatic memories of mixing even these two siblings in a stack!

Hi Thanks to all that contributed to this, In the end we went with the 5530 -24 and two 10GB MM fibre xfpthen used OM4 MM fibre, We kept the switch as a stand alone with two copper links as an MLT into the stack. this seems to work for now,
